Levels are much higher than<10210mol/kg H2Ofrompreviousestimatesand close to or higher than∼1026mol/kg H2O in modern Earth seawater. Ocean acidification is the decrease in the pH of the Earth’s ocean. Between 1950 and 2024, the average pH of the ocean surface fell from approximately 8.15 to 8.05. Carbon dioxide emissions from human activities are the primary cause of ocean acidification, with atmospheric carbon dioxide (CO2) levels exceeding 410 ppm (in 2024). CO2 from the atmosphere is absorbed by the oceans. This prod…

WebbAs atmospheric levels of CO 2 have increased, the CO 2 content of the ocean water has also increased, leading to a reduction in seawater pH. Some models suggest that at the current rate of CO 2 addition to the atmosphere, by 2100 ocean pH may be further reduced to around 7.8, which would represent more than a 120% increase in ocean acidity since … pooler theater with reclinersWebb16 feb. 2024 · The average global ocean pH has fallen from 8.11 in 1985 to 8.05 in 2024.
